A catalytic, RTV silicon rubber skin mold for the making of small wax skulls.
Or another medium if such were desired. Polyester, acrylic, cements, reconstructed media, the choices are many and varied.
Here the ‘master’ is being withdrawn from the rubber ‘skin. This rubber is a very strong, tear resistant, flexible substance and when designed well for such a mold as this will be capable of innumerable reproductions before deterioration renders it unusable.
The master pattern released and the rubber ready for wax.
